The invention discloses a reactive permeable tack coat material special for water permeable pavement. The reactive permeable tack coat material is composed of a component A and a component B, whereinthe component A comprises the following components in parts by weight: 30-50 parts of end-NCO group-terminated polyurethane prepolymer, 40-50 parts of penetrating fluid, 5-10 parts of SBS, 2-5 parts of petroleum resin, 3-8 parts of natural rosin resin, 0-1 part of flame retardant and 1-3 parts of diluent; the component B comprises the following components in parts by weight: 100 parts of a polyolcuring agent and 1-3 parts of a catalyst. The tack coat material provided by the invention is a reactive permeable tack coat material specially applied to permeable pavement, which greatly improves adhesion and durability, in particular, the tack coat material has good permeability for the permeable pavement with macropores, does not block pores, has small system viscosity, and strong adhesion, and is simple in preparation process, economic and durable.
